Description: The eBioSAM-1 monoclonal antibody reacts with human integrin alpha 5, also known as fibronectin receptor alpha chain, very late activation antigen 5 alpha, and CD49e. Integrins are composed of an alpha chain and a beta chain, which non-covalently associate to form the functional integrin. Integrin heterodimers participate in cell surface-mediated signaling and adhesion functions. Integrin alpha 5 undergoes post-translational cleavage in its extracellular domain to yield disulfide linked light and heavy chains that join with Integrin beta 1 (CD29) to form the fibronectin receptor, also known as the very late activation antigen-5 (VLA-5) complex. Integrin alpha 5 is expressed on thymocytes, T cells, monocytes, platelets, early B cells, and activated B cells.
